Ask HN: Startup - best way to promote?

Hello Everyone!

We just launched our site at http://www.cbuy.tv

From experience, what is the best way to get traffic to a new site, aside from SEO and PPC? Your suggestions would be a huge help.

P.S. Feedback through our onsite feedback tab would be a huge help if anyone is willing! Please share the site too:)

What we do: CBuy makes it easy to dress like a star. Ever wonder what your favorite celebrity was wearing in the latest paparazzi photo or in your favorite TV episode? If so, you can buy it at CBuy - see it, buy it!
